New Channel Guide is not user friendly.

What is going on with the Channel guide? 2 of my 5 Roku sticks have updated to this new Channel guide. It sucks!! I have to pick my profile every time I turn on the tv. The arrow back key will not let me bounce between 2 channels any longer. At times I may be watching 2 shows. When I arrow back it will only take me to the guide. Is ROKU trying to make their guide look like every other app guide? I have looked all over trying to figure out how to put it back to the original guide but no luck so far in figuring it out. The other day I was watching tv and using the original channel guide. Turned off tv and then when I came back turned on tv and it sat there with the spinning circle like it needed to be unplugged and rebooted. I did that and then all my profiles came up and I selected mine and then I got this new channel guide. I hate it. There was nothing wrong with the original channel guide. Please advise if anyone knows how to go back to the old channel guide?
